<br>
<b>function</b> IsLinkedTo(DataSource: TDataSource): Boolean;
<br>

<br>
<b>Description</b>
<br>
Call IsLinkedTo to verify that a dataset is linked to a specific data source. DataSource is the name of the data source against which to test.
<br>

<br>
<b>Note:</b>&nbsp;&nbsp;&nbsp;IsLinkedTo is mainly provided for developers deriving custom components based on TDataSet. It is not intended or needed for general data access.
<br>

<br>
If the datasource already provides data from the dataset or one of its nested dataset fields (or a nested dataset nested in a dataset field...),  IsLinkedTo returns True. If the datasource provides data from some other dataset, or if the data source does not already have a dataset of its own, IsLinkedTo returns False.
